The King: From today, I shall continue, preserve, and build upon the royal legacy and shall reign with righteousness for the benefit and happiness of the people forever. The Chief Brahmin: Your Majesty, I do receive this the first command of yours, and will fulfill it to the best that I can do.^{[citation needed]}
